Question: 1 / 400

When measuring blood pressure, which artery is commonly used in the upper extremities?

Radial artery

Femoral artery

Brachial artery

The brachial artery is the standard site for measuring blood pressure in the upper extremities because it is centrally located and provides a reliable reading that reflects the pressure in the larger arteries of the body. The brachial artery is typically found in the arm, just above the elbow, and is easily accessible, allowing for effective auscultation with a stethoscope and inflation of a sphygmomanometer.

Measuring blood pressure at this site allows for standardized readings across different individuals and situations, minimizing variability and ensuring accuracy in clinical assessments. This method is well-established in both clinical practice and guidelines, making it the preferred choice for blood pressure measurement in the upper extremities.
